`MediaBrowserServiceCompat` from version 23.2.0 to 23.4.0 of the Support
v4 Library used private APIs and will not be compatible with future
versions of Android beyond Android N. Please upgrade to version 24.0.0
or higher of the Support Library.

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
build.gradle:4:Warning: Using a version of the class that is not forward
compatible [IncompatibleMediaBrowserServiceCompatVersion]
    compile 'com.android.support:support-v4:23.4.0'
             -------------------------------------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here are the relevant source files:

`src/test/pkg/MyBrowserService.java`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~java linenumbers
package test.pkg;

import android.os.Bundle;
import android.support.v4.media.MediaBrowserCompat;
import android.support.v4.media.MediaBrowserServiceCompat;

import java.util.List;

public class MyBrowserService extends MediaBrowserServiceCompat {

    @Override
    public BrowserRoot onGetRoot(String clientPackageName, int clientUid, Bundle rootHints) {
        return null;
    }

    @Override
    public void onLoadChildren(String parentId, Result<List<MediaBrowserCompat.MediaItem>> result) {

    }
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`build.gradle`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers
apply plugin: 'com.android.application'

dependencies {
    compile 'com.android.support:support-v4:23.4.0'
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test
found for this lint check, `MediaBrowserServiceCompatVersionDetector.testMediaBrowserServiceCompatOldVersion`.

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Using a suppression annotation like this on the enclosing
  element:

  ```kt
  // Kotlin
  @Suppress("IncompatibleMediaBrowserServiceCompatVersion")
  fun method() {
     problematicStatement()
  }
  ```

  or

  ```java
  // Java
  @SuppressWarnings("IncompatibleMediaBrowserServiceCompatVersion")
  void method() {
     problematicStatement();
  }
  ```

* Using a suppression comment like this on the line above:

  ```kt
  //noinspection IncompatibleMediaBrowserServiceCompatVersion
  problematicStatement()
  ```

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="IncompatibleMediaBrowserServiceCompatVersion" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'IncompatibleMediaBrowserServiceCompatVersion'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore IncompatibleMediaBrowserServiceCompatVersion ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
